t3404: modernize here doc style

In 't3404-rebase-interactive.sh' the expected output of several tests
is prepared from here documents, which are outside of
'test_expect_success' blocks and have spaces around redirection
operators.

Move these here documents into the corresponding 'test_expect_success'
block and avoid spaces between filename and redition operators.
Furthermore, quote the here docs' delimiter word to prevent parameter
expansions and what not, where applicable.
