[Feature] Upgrade to Cypress 4

[warpech]

Current behavior:

This plugin requires Cypress 3.x.x according to

cypress-file-upload/package.json

Line 45 in 9df046c

"cypress": "^3.0.0"

.

Desired behavior:

I wish the plugin is updated to work with the current version of Cypress, which is 4.0.1.

Thanks for a great plugin! 👋

Hi @warpech
Thanks for submitting the issue!

I am really happy that the plugin went so widely used among the community 😃
With regards to new version I expect a bunch of issues either related to v4 itself or cross-browser compatibility (like #154)

So I would expect having proper tests and fixing all ongoing issues until the end of February.

Stay tuned! 🌟

For us, all of our tests, including the ones that used cypress-file-upload to upload an image to a form using https://www.dropzonejs.com/, worked flawlessly with Firefox and Cypress v4 ☺️

We merely ignore the warning generated by the peer dependency requirement of cypress-file-upload for now

Given I have:

• yarn version 1.21.1;
• cypress-file-upload version 3.5.3;
• cypress version 4.0.2.

When I run yarn install

Then this is Terminal output:

[1/5] 🔍  Validating package.json...
[2/5] 🔍  Resolving packages...
[3/5] 🚚  Fetching packages...
[4/5] 🔗  Linking dependencies...
warning " > cypress-file-upload@3.5.3" has incorrect peer dependency "cypress@^3.0.0".
[5/5] 🔨  Building fresh packages...

success Saved lockfile.
✨  Done in 21.57s.

Process finished with exit code 0

But this should be the Terminal output:

[1/5] 🔍  Validating package.json...
[2/5] 🔍  Resolving packages...
[3/5] 🚚  Fetching packages...
[4/5] 🔗  Linking dependencies...
[5/5] 🔨  Building fresh packages...

success Saved lockfile.
✨  Done in [...]s.

Process finished with exit code 0

For now I'm ignoring the warning (like @valscion said)...
...but it would be better if this warning does not appear.
