Fixed some log dependency issues. Fixed the possible problem with cache that we found (but we didn't get evidences of the root cause). It need to finsih an unit test but I don't have enough knowledge about LDAP and Apache DS API, if someone could help with that, I can update this PR

@luan-cestari does this fix #116? And is there any more work to do before review? Your last comment makes me think something needs done with a unit test still.

[luan-cestari]

@jewzaam it probably solve it as we don't have enough data about the issue, so I wouldn't guarantee it solves the problem. The remaining test is something good to have, I ping some people on the channel for help, I think Derek is working on it.

[jewzaam]

Condition should be !userRolesFromCache.isEmpty() (missing !)

[jewzaam]

I'll merge after condition for using roles from cache is update.
Per note in this PR and @derek63 working on something for the unit test I am skipping review of the test. I'll expect a separate PR coming with heavy updates.
