Changed code to improve output messages on error for files under test/e2e/apps (#109944)

* Improving the output of tests in case of error

* Better error message

Also, the condition in the second case was reversed

* Fixing 2 tests whose condition was inverted

* Again I got the conditions wrong

* Sorry for the confusion

* Improved error messages on failures
