When adding MERGED_TP_J1_OSTM_OST_CYCLES_V52 to HiTIDE UAT it breaks HiTIDE, update HiTIDE to not fail when this happens but make a warning

[jamesfwood]

For some reaason when adding MERGED_TP_J1_OSTM_OST_CYCLES_V52 to UAT MMT for HiTIDE UAT, HiTIDE has an error:
"Unable to load configuration, initial dataset listing not found."

Please investigate why this happens, and fix the issue.
And also update HiTIDE so it doesn't completely break the UI, but just gives warnings.
Like a pop up that says could not load these collections:

or on the collections list of the count, add another item for failed collections, like

81 collections, 1 error

and have it so you can hover over the error and see which collections are failing.
