Save session after browse()

[luukvbaal]

save_session() after returning from browse() since this was skipped by the picker mode SEL_OPEN control flow:

nnn/src/nnn.c

Line 6827 in 2435263

return EXIT_SUCCESS;

I think this fixes mcchrish/nnn.vim#109 without any side-effects.

Thank you!

Just noticed the session is not saved when nnn is started with a path as arg i.e. nnn -S -s test /home.

I think its a fair assumption that if both -S -s session and a initpath are given, the initpath should have precedence(as is the case), but the session is still saved on exit which is currently not the case.

Or even just when the sessionfile doesn't exist yet i.e. when the session fails to load. I think this would be desirable behavior.
