[mssql] [bug] The "SELECT SERVERPROPERTY"
query added in #3810 and #3814 is failing on unknown
combinations of Pyodbc and SQL Server. While failure of this function
was anticipated, the exception catch was not broad enough so it now
catches all forms of pyodbc.Error.
[bug] [core] Changed the CompileError raised when various primary key missing
situations are detected to a warning. The statement is again
passed to the database where it will fail and the DBAPI error (usually
IntegrityError) raises as usual.
