Bug fix in prepare.py

[Waschina]

In the block that constructs the DIAMOND database, there was a small bug in the logging (line 118):

CAT_pack/CAT_pack/prepare.py

Lines 116 to 125 in 94f2dee

	try:
	message = "Running command: {0}".format(" ".join(command))
	give_user_feedback(message, log_file, quiet)
	subprocess.check_call(command)
	except:
	message = "DIAMOND database could not be created."
	shared.give_user_feedback(message, log_file, quiet, error=True)
	sys.exit(1)

The bug caused that the prepare workflow stopped with

ERROR: DIAMOND database could not be created.

without further details on the cause of the error in the log files.

Prepending the shared. in calling the function give_user_feedback fixes the bug.
