Read correct process_methods from config on startup

On startup, init will overwrite previous values set for process_method_torrent and process_method_nzb because it's actually reading process_method for each setting.

This change fixes that by setting PROCESS_METHOD_NZB and PROCESS_METHOD_TORRENT to read from the correct string within config.

For quick reference, the config names for the specific process methods:

Medusa/medusa/__main__.py

Lines 1714 to 1715 in 49ad1f9

	new_config['General']['process_method_torrent'] = app.PROCESS_METHOD_TORRENT
	new_config['General']['process_method_nzb'] = app.PROCESS_METHOD_NZB

Good catch, thank you!
