Multi-Mapping SplitOn spaces between commass

There was a small issue when SplinOn spaces between commas, for example:
splitOn: "AddressId, Id".
For more info see:
http://stackoverflow.com/questions/11042618/dapper-multi-mapping-issue

I have modified below line of code:
From: var currentSplit = splits[splitIndex];
To: var currentSplit = splits[splitIndex].Trim();

Also added a test called:
TestMultiMappingWithSplitOnSpaceBetweenCommas()
