Ștefan Talpalaru 7dfb2a8cd3 fix segfault when calling shallow() on an empty string (#9782) [backport] ...

shallow() casts its string argument to a seq and then tries to access
its fields. Guess what happens when that string is nil, which seems to
be the representation of an empty string (both the default value and an
explicitly assigned "").

Segfault encountered when running "ntags -R ." on a large project. The relevant line:
a1c62c38e5/ntags.nim (lines-125)

(cherry picked from commit f8fa94cb20)
