*cider-test-report* undo-outer-limit warning

[boxxxie]

Expected behavior

(cider-test-run-project-tests) should print out test data to cider-result

Actual behavior

``` *Warnings* buffer output
Warning (undo): Buffer ‘cider-test-report’ undo info was 25019134 bytes long.
The undo info was discarded because it exceeded `undo-outer-limit'.

This is normal if you executed a command that made a huge change
to the buffer. In that case, to prevent similar problems in the
future, set `undo-outer-limit' to a value that is large enough to
cover the maximum size of normal changes you expect a single
command to make, but not so large that it might exceed the
maximum memory allotted to Emacs.

If you did not execute any such command, the situation is
probably due to a bug and you should report it.

You can disable the popping up of this buffer by adding the entry
(undo discard-info) to the user option warning-suppress-types', which is defined in the warnings' library.
