DOCK-2464: Display ignored lambdaevents appropriately

[svonworl]

Description
This PR changes the GitHub Apps lambda event table so it displays "Ignored" in the "Success" column when the LambdaEvent's ignored property is true. Otherwise, the UI remains the same.

Additionally, it fixes a "search" smoke test failure which was induced by a recent search change that turns underscores into token breaks. Now, ES will split the search term "dockstore_i" into two words at the underscore, so, in addition to returning literal matches, it will return matches for either of the component words, ranked lower. Before, a search for "dockstore_i" returned no results, and now it returns some, breaking the tests. The PR changes search term "dockstore_i" to another nonexistent word "dhockstore" that doesn't include underscores.

Review Instructions
Install the github app on a repo, do two pushes to it in rapid succession (within 20 seconds of each other), wait five minutes, view the Apps Logs, and confirm that two new events have appeared, one of which should be marked "Ignored".

Please make sure that you've checked the following before submitting your pull request. Thanks!

• Check that your code compiles by running npm run build
• Ensure that the PR targets the correct branch. Check the milestone or fix version of the ticket.
• If this is the first time you're submitting a PR or even if you just need a refresher, consider reviewing our style guide
• Do not bypass Angular sanitization (bypassSecurityTrustHtml, etc.), or justify why you need to do so
• If displaying markdown, use the markdown-wrapper component, which does extra sanitization
• Do not use cookies, although this may change in the future
• Run npm audit and ensure you are not introducing new vulnerabilities
• Do due diligence on new 3rd party libraries, checking for CVEs
• Don't allow user-uploaded images to be served from the Dockstore domain
• If this PR is for a user-facing feature, create and link a documentation ticket for this feature (usually in the same milestone as the linked issue). Style points if you create a documentation PR directly and link that instead.
• Check whether this PR disables tests. If it legitimately needs to disable a test, create a new ticket to re-enable it in a specific milestone.
