TAB doesn't work in stacktrace-mode

[raxod502]

tl;dr <tab> bound but not TAB in stacktrace buffers.

Here are the keybindings in stacktrace-mode according to C-h m:

Stacktrace mode defined in ‘cider-stacktrace.el’:
Major mode for filtering and navigating CIDER stacktraces.

M-n             cider-stacktrace-next-cause
M-p             cider-stacktrace-previous-cause

As you can see, <tab> is bound but TAB is not. This has the consequence that cider-stacktrace-cycle-current-cause can't be triggered in the terminal, since TAB is sent instead of <tab>.

This should be a pretty simple fix (just bind TAB in addition to <tab>).
