File resume with CLI output is inconsistent

[bwalkerl]

When a search is called from the CLI the output has to be specified. If the output is the same as an existing file, this will attempt to "resume" from that file, which may not be intended.

Our options here are to either change how output it handled (these searches are saved in the UI

• Make output optional (should no longer be mandatory since it can be viewed in the UI)
• Differentiate CLI outputs. This could be done by either adding extra checks or always generating the file used in the GUI and copying the output file at the end.
