testing: fix CI failures

[katcipis]

Right now CI is failing all the time on tests that when I run isolated works perfectly on my host. But when I try to run all tests I get some intermittent errors that seems be caused by azure instability x_x.

The current approach to try again is flawed because almost all errors leave the state on a unrecoverable state =(. This has to be fixed for the tests to remain useful.
