Get by key value is broken, must use Get by object

[kspdrgn]

Sorry if this is a duplicate. Maybe this will help other developers running into this issue.

Using Get as the documentation suggests Get(id) doesn't work, it doesn't generate any predicate. Must use Get(new { id }) syntax.

This bug may affect all providers, I have only tested SQL Server.

The predicate is not filled out when using Get(value) but they work when using Get(object). I noticed that in DapperImplementor.GetMapAndPredicate, GetKeyPredicate is only called for Update and Delete, not Get.

Workaround for developers is to use Get(new {}) syntax.

Workaround for Dapper-Extensions may be to fix the documentation to say Get(new { id }) instead of Get(id).

See pull request with a corrected test case that shows Get is failing
