Description of problem:
When httpd fails to start for any reason, it tells users they likely need to run pulp-manage-db, even when that's not the case. This leads to lots of confusion and just isn't helpful. Also, it is possible for it to detect for sure whether pulp-manage-db needs to be run, so it should give the user the real error.

Version-Release number of selected component (if applicable):
2.4.0-1

How reproducible:
Every time

Steps to Reproduce:
1. Break Pulp in some way, perhaps by inserting a raise Exception during its initialization.

Actual results:
It will tell you that you likely need to run pulp-manage-db.

Expected results:
It should tell you what really happened.

Additional info:
Of course, if it really is that you need to run pulp-manage-db, it should tell you that, without the word "likely".
