Error applying patch 54 on clean qiita install

[AmandaBirmingham]

Following the procedure in https://github.com/qiita-spots/qiita/blob/4492c3d53027a9387931b2449a705dd3b1c8f09f/INSTALL.md , after running qiita-env make --no-load-ontologies, I receive the following non-fatal error:

<other patch applications above>

	Applying patch 54.sql...
		Applying python patch 54.py...
Error purging filepaths: [Errno 2] No such file or directory: '/Users/abirmingham/Work/Repositories/qiita/qiita_db/support_files/test_data/FASTQ'

<other patch applications below>

It looks like the originates from

qiita/qiita_db/support_files/patches/python_patches/54.py

Lines 692 to 696 in 4492c3d

	# Purge filepaths
	try:
	purge_filepaths(False)
	except Exception as e:
	errors.append("Error purging filepaths: %s" % str(e))

but I can't tell more than that.

Not sure how to proceed; that message is accurate because the folder doesn't exist; the error doesn't stop execution but is logged - in other words, it should really be a warning. However, that patch is old and it doesn't really do anything on a fresh install. @AmandaBirmingham, what do you think it should happen? Maybe add a line in INSTALL.md about this?

[AmandaBirmingham]

Are there other situations where the folder does exist? If no, I think the error message should be suppressed. If yes, I think that the INSTALL.md should be extended to include a sentence about how this error is expected on a clean install and can be ignored.

Merging this #3403 fixed this issue.
