It is still mysterious.

Reproducing the test locally (remote host runs Ubuntu, but it
shouldn't matter) shows:

# Setting shell prompt
$ PS1='
///69b9edf343eb473008d721d21a951698
'; PS2=''; PS3=''
$ echo ~root
/
# Remote `/bin/sh' groks tilde expansion, good
# Finding command to check if file exists
$ test -e / 2>/dev/null; echo tramp_exit_status $? 
tramp_exit_status 0
$ test -e /\ this\ file\ does\ not\ exist\  2>/dev/null; echo tramp_exit_status 
$? 
tramp_exit_status 1

...

And looking at the code, there is no reason that Tramp shouldn't raise
(and trace!)  the next command 'test -e / 2>/dev/null; echo
tramp_exit_status $?'

Hmm. Could you, please, restart Emacs with "emacs -q"? Then apply

(setq debug-on-error t
      debug-on-quit t)

and rerun the test please. It should give you a backtrace, which might
be helpful.

Best regards, Michael.
