"Octal" digits warn twice.

If I write something like `say 09`, Rakudo warns about octal numbers
twice. Also, "octal" numbers don't work in REPL.

<masak> GlitchMr​: the phrase "don't work" is generally taboo in bug
reports.
<GlitchMr> sorry
<masak> GlitchMr​: you should be talking about what you did, what you
observe, and what you expected.
<GlitchMr> Null PMC access in get_string()
<masak> right. that should be in there.
<masak> GlitchMr​: the goal is to have enough information that the thing
can be checked again later.

By REPL not working, I mean that every time octal number appears, "Null
PMC access in get_string()" appears. Sorry for not mentioning that
initially.

Fresher test results​: no duplicate warnings, NULL pointers in REPL
under parrot and jvm but not moar. Probably LTA to be telling the
user to use '0o8' or '0o9'.

This works as expected in the REPL and out. Can be closed with tests.
