Added tests and test input/output for the team_info transform

[jaclynbeck-sage]

This test has 4 test cases, all of which should pass. There are no failure cases for this transform, as the transform is simple and doesn't care what the values are in each column. Since the data in the original team info source files is hand-curated and small, we assume that the contents of each column have been validated by the person curating the file, prior to the transform.

I made the test files to have values with a few properties, some of which are not explicitly tested by this test but may be useful in future:

• missing a value in various columns
• punctuation in the team names and people names
• special characters in the URL fields (which I verified made it through standardize_values intact)
• One team with multiple isprincipalinvestigator TRUE values (which happens in the real files)
