Stacktraces don't filter mocha when minified

[brian-lagerman]

Prerequisites

• Checked that your issue hasn't already been filed by cross-referencing issues with the faq label
• Checked next-gen ES issues and syntax problems by using the same environment and/or transpiler configuration without Mocha to ensure it isn't just a feature that actually isn't supported in the environment in question or a bug in your code.
• 'Smoke tested' the code to be tested by running it outside the real test suite to get a better sense of whether the problem is in the code under test, your usage of Mocha, or Mocha itself
• Ensured that there is no discrepancy between the locally and globally installed versions of Mocha. You can find them with: node node_modules/.bin/mocha --version(Local) and mocha --version(Global). We recommend that you not install Mocha globally.

Description

When running tests in the browser, the stackTraceFilter removes lines containing mocha.js as designed. This fails when using a minified version (from cdnjs) of mocha, as mocha.min.js is not tested for.

Steps to Reproduce

Swap
<script src="https://cdnjs.cloudflare.com/ajax/libs/mocha/6.1.4/mocha.js"></script>
to
<script src="https://cdnjs.cloudflare.com/ajax/libs/mocha/6.1.4/mocha.min.js"></script>

in the default html template, and view the stacktrace for a failing test.

Expected behavior: mocha is remove from the stack

Actual behavior: mocha exists (loudly) in the stack

Reproduces how often: 100%

Versions

• 6.1.4

Additional Information

I have a fix prepared. It can be corrected with a one line addition to isMochaInternal with || ~line.indexOf(slash + 'mocha.min.js'). PR should be forth coming.
