srm: Fix renaming of count column

Motivation:

The attempt to rename the oddly capitalized count column of the lsrequests
table didn't work as liquibase itself escaped our quotes.

Modification:

Since the other columns are already lower case in postgresql and since
our HSQLDB databases are always recreated for testing, this patch drops
the changeset entirely.

Result:

SRM schema migration of existing schema works.

Target: trunk
