Renamed sql file to enable autoinstall

[biosfree]

Changes Proposed:

• Renamed sql file to enable autoinstall sql
• Since the Commits: f3d285e didn't help fix the auto-installation of the sql file when starting worldserver

Tests Performed:

• place the module under the modules directory of your AzerothCore source.
• Re-run cmake and launch a clean build of AzerothCore
• Started worldserver and mod_auctionhousebot.sql was automatically added to the acore_world database

How to Test the Changes:

worldserver started without error
