t5551: fix the 50,000 tag test

The first version of test 23 did simply check that no output was
sent to the standard error stream.  With 5e2c7cd (t5551: do not use
unportable sed '\+', 2013-05-12), we started to also verify that the
expected tags were actually cloned.

Since 68b939b (clone: send diagnostic messages to stderr,
2013-09-18), "git clone" shows "Cloning into 'too-many-refs'" to the
standard error stream (it used to do so to the standard output),
causing the test to fail.
