app: consistently use t.Fatal* instead of t.Error* (except of app/vmalert and app/vmctl - these packages will be processed in a separate commit)

Browse Source 
Consistently using t.Fatal* simplifies the test code and makes it less fragile, since it is common error
to forget to make proper cleanup after t.Error* call. Also t.Error* calls do not provide any practical
benefits when some tests fail. They just clutter test output with additional noise information,
which do not help in fixing failing tests most of the time.
