Check constraints repeated multiple times

[feilbaca]

Hi,
I've found another issue with exporting from SQL Server:

Many of our tables have one or more check constraints, and on checking the SIARD file after export, I noticed that each of these constraints seemed to have been read and added multiple times. After a bit of experimenting I figured out that this only happens with constraints that call a user-defined function with more than one parameter, and then each constraint gets added once per parameter. For example:

<checkConstraints>
    <checkConstraint>
        <name>Check_tbTestTable_Test</name>
        <condition>([dbo].[udfTestFunction]([TestTable_ID],[TestTable_Int])=(1))</condition>
	</checkConstraint>
	<checkConstraint>
		<name>Check_tbTestTable_Test</name>
		<condition>([dbo].[udfTestFunction]([TestTable_ID],[TestTable_Int])=(1))</condition>
	</checkConstraint>
</checkConstraints>

I've checked this with varying numbers of params and it happens every time.

Tested with dbptk v4.3.1 from the command line.
