Update filter persistence test to remove data dependence

[mrtopsyt]

Need

Currently the testFilterPersistence function in testFunctions.ts fails if the first filter value does not have associated text.
The current test runs as follows:

• Go to the specified "first" tab
• Click the specified filter
• Click the first filter value. If the first filter option is blank, print a warning and fail.
  • This is necessary under the current structure because without test ids, there is no way of selecting a filter without text in future steps
• Record the name of this filter
• Expect at least one table cell to be visible
• For each specified "other" tab
  • Click the tab
  • Select the same filter as before
  • Expect the filter value with the name that was recorded earlier to be checked
• Click the specified "first" tab
• Expect at least one table cell to be visible
• Click the same filter as before
• Check that the filter option is still checked
• If no issues are encountered, pass the test

Approach

• Change the test to continue to check filter values until it finds the first filter value that has associated text. Fail if after a specified number of filters is checked, none has text
