Fix yaml snapshot specification with data tests

[gshank]

Resolves #11110

Problem

We were writing the compiled version of the snapshot node to the yaml file name, so that when generic tests were written out the "directory" was a file. In addition multiple snapshots nodes would have been written to the same output file.

Solution

Construct the yaml snapshot compiled path including the "name" + ".sql" of the snapshot node.
