When the process it tries to read the working dir from has exited,
then "/proc/PID/cwd" is an invalid link and fs.readlink() will reject
its promise with an error.

This results in the terminal "new tab" and "new pane" buttons stopping
working, which is very disruptive :(

This commit makes sure that the "new tab" and "new pane" buttons keep
working, whatever happens.
