Bug 1130121

Description of problem:
https://pulp-dev-guide.readthedocs.org/en/latest/conventions/exceptions.html#error-details

There is a discrepancy in the state of the task's status and information that is hold in the error details.
State of the task is 'finished' though  the 'error' contains "PLP0007"" error code that tells us about some pulp error( from docs: The following segments have been established * PLP0000-PLP0999 - General Server Errors (and legacy PulpException errors))

Note: the repo is deleted normally.
