Ftrack: Action delete old versions formatting works

[iLLiCiTiT]

Brief description

Fixed formatting of representation path with frames.

Description

Arguments for StringTemplate were swapped which caused a crash.

Testing notes:

1. Run the action from Ftrack on representation with frames
2. Action should delete files without any issues

Traceback

==============================
<StringTemplate> argument must be a string, not <class 'dict'>.
