ezplot (@(x) 2)

error: called from
    __ezplot__>find_valid_domain at line 508 column 7

Observed on 0.8.4 and dev tip from a few weeks ago.

This is sort of a dupe of
https://savannah.gnu.org/bugs/?func=detailitem&item_id=49766
which was closed fixed but taking a closer look, there were 2 ways it could
fail and we fixed only one of them,

It is downstream issue: https://github.com/gnu-octave/symbolic/issues/1318
