Increase timeout for mocha to 7500

[grisu48]

In order to fix some timeout issues in the CI on low-end hardware we increase
the timeout for mocha to 7500ms.

This is a proposed fix for #4886

Thanks @grisu48 ! The particular test referenced in the issue can take a bit due to the memory allocation for it. Is that the only test that times out? If so, I can update your PR to isolate the expanded test timeout only to that single test.

Yes, the rest of the CI works nicely with this timeout. With the here provided fix, the following test runs completes without any errors:

npm config set shrinkwrap false && npm rm --silent --save-dev connect-redis && npm run test-ci

The should not stack overflow with many registered routes test clocks in at ~3700ms, therefore we doubled this duration and came up with the suggested 7 seconds.

Important: Since the CI test runs cancels after the first failure, I cannot comment if other tests are not affected yet. Will look on Monday at the logs and try to determine if other tests are affected as well.

@dougwilson I adapted your solution and tested in on my affected aarch64 VM, where 5/5 test runs are now passing. Please review again, IMHO this would solve the issue.

Thank you for merging! 🙂 👍
