Update Tests for better pandas df snapshots

[jcharkow]

Issue:

Currently, snapshots using a pandas dataframe seem to be broken to me as it is not actually checking the entire dataframe just sections of this.

One option I've considered is converting to dictionaries however sometimes tests still fail because dictionaries have no order in their columns.

Currently, the best solution I can find is using a custom extension of syrupy which allows for snapshots with pandas dataframes. I am currently working on that in the https://github.com/Roestlab/massdash/tree/test/add_tests branch.

This would require additional dependencies of pytest and syrupy however I think it is worth it. @singjc @irahorecka please let me know your thoughts

@jcharkow @irahorecka I think we should add unittests for the main stream app as well.

Closing this because Pandas Df snapshots have been added. Note: We still have to do streamlit tests
