Bug/246 filter selection disappearing

[rjgallego]

Fixing filter selection disappearing on back button

Filters regenerate every time the hub images are fetched from redux. When back button is selected, the selected filter is still saved in the state but the values are regenerated with default of undefined which is then set to false. Following updates made to convertArrayToFilterObject to fix issue:

• Remove 'false' from or statement (value for filters will default to undefined)
• Check if filter does not contain values already
• If there are no values already, check if passed image array has size of 1 (i.e. a filter is selected), if so expression will evaluate to true and filter will be given a value of true

Also added an integration with cypress to verify that the filter is still selected (surrounded by blue border) after going to prior page then returning

Closes #246
