Add junit.xml to gitignore

[dottorblaster]

Description

Right now a junit.xml file gets generated upon npm test, I'm just adding it to the gitignore in order to avoid committing it by mistake.

In case you want to consider this alternative: There is also an option that can be set under jest-junit in jest.config.js:

outputDirectory: "/tmp"

Thanks for looking into this. It escaped my attention and should have been handled in a way similar to the mix tests, when I introduced these junit deps.

No worries @gagandeepb, I just stumbled upon this right now. Can you do the same for the other tests?

[gagandeepb]

For the other categories of tests: mix tests already have an opt-in flag (WRITE_JUNIT=1) to generate the junit so they do/should not generate junit files by default. Even when opted-in, the junit files for mix tests go to /tmp by default.

[gagandeepb]

For jest tests, the write destination of the junit files can also be customized/overridden, if needed, like: JEST_JUNIT_OUTPUT_DIR=$DESIRED_DIRECTORY npm test

LGTM, but lol that's random... isn't that Java normally?
