Someone (Eric IIRC) suggested using double-quotes around the last
argument of test_expect_success. Even though I'm the one who suggested
this ${sq}, I have to agree with this suggestion. The result looks like

test_expect_success 'alignment with quote' "
	cat >expect <<-\EOF &&
	refname is '               '\\'''master'\\''
	...
"

Because you used "" at the toplevel, ' is not a special character
anymore. You do have to be careful with \\ though, but adding before EOF
as I did should do the trick. Untested.

You don't have test for nested alignment with quotes. I think it
deserves to be tested, if only to cast in stone that the current
behavior is your intention.

Perhaps just adding --shell to the test below would be OK to avoid the
proliferation of tests :
