Cache file seems to be mandatory

[canasdiaz]

We're having errors with a corrupt cache file. A cache file shouldn't be mandatory, if it is not present, it should be updated by cvsanaly and never a mandatory requirement.

pycvsanaly2.DBContentHandler.CacheFileMismatch:
Cache file /home/owl/.cvsanaly2/cache/https:__github.com_openstack-infra_devstack-gate.git 
is not up to date or it's corrupt: Commit id mismatch for revision cbb031a3fd0cb0b30d4e901a4a5313b1e91c333a (File Cache:25796, Database: 74265). 
It's not possible to continue, the cache file should be removed and the database cleaned up

We saw this error comparing the result of the incremental mode and running cvsanaly from scratch using different databases, same user and a copy of the git clones.
