3.4 release is broken - includes a rogue line

[simonw]

I started seeing weird errors, caused by this line:

sqlite-utils/sqlite_utils/cli.py

Lines 1 to 3 in f8010ca

	import base64
	from tests.test_cli import test_query_memory_does_not_create_file
	import click

That was added by accident in 1b666f9

I'm surprised the tests didn't catch this!
