Account for flaky invocationDetails presence in Cypress tests

[kschiffer]

Summary

This quickfix PR will ensure that the fail fast logic of the cypress tests does not result in further crashes.

Changes

• Account for invocationDetails not being in the context which can sometimes be the case

Testing

• Manual testing, this is a pure dev tooling change

Notes for Reviewers

It appears as though the invocationDetails can sometimes be missing from the context. More info on that here:
cypress-io/cypress#3090 (comment)

So I believe it's best to add a check for it and just run the remaining tests anyway if necessary. It should be noted that this bit of the fail-fast logic only fires when the connected test already failed organically. So typically the logic should not result in a test failure in itself, but it can obfuscate the actual failure of the underlying test.
