[fish] exit as well when called from non-interactive shell (#3467)

Browse Source 
Just like with the other shells, exit fish to, if called from a non-interactive
shell.

We cannot use `return`, as older versions of fish (namely < 3.4.0) did not
support to use `return` in `.`-scripts (this was only added with fish commit
3359e5d2e9bcbf19d1652636c8e448a6889302ae).

Unlike in POSIX, fish’s `exit` is however documented to no cause the calling
shell to exit when executed in a sourced script (see:
0f70b2c0d3/doc_src/cmds/exit.rst (L20)
)
