[BUGFIX] mssql: ExpressionBuilder inSet() support

mssql does not support FIND_IN_SET(). The patch adds a
solution based on LIKE.
Since the query fiddling in this area is a bit tricky,
this area is now supported by a bunch of functional tests.
A postgres bug those new functional tests reveal is fixed
along the way.
