Bug 9455: Remove unnecessary quoting from sql

Wa've removed the mysql specific back quotes from sql files
But this case remained of them embedded in an sql string
Also removed the unnecessary call to finish
and temporary variable in the subroutine return

Testing: Functionality should remain unchanged. Retrieval of
basketgroups in acquisitions should not be affected

Works according to test instructions: Basketgroups
functionality appears to work normally.

Checked SQL produces the same results as before and did some
tests on the basket group functionality.
