[BUGFIX] DBAL: Fix quoting of single quotes in WHERE values for MSSQL

MSSQL escapes single quotes in values by doubling them. When parsing the
WHERE clause DBAL removed the escaping without performing the required
escaping of the values when compiling the query. This is fixed by adding
a special handling of MSSQL in _quoteWhereClause().
