trying to ingest files w similar names results in errors

[mcampos-quinn]

redo the form parsing for ingestor so that filenames that contain the names of other files, eg

thisIsAFile.mov
AndthisIsAFile.mov

currently this tries to get both files even if only one is selected and there's a problem parsing stuff down the line since the ingestor doesn't know which is which.

i think this is happening in the parsing of toIngest list in ingest.views.py

This is solved on ingest-refactor where the ingest form parsing is handled differently
