[Koha-patches] [PATCH] [SIGNED-OFF] ModBookseller needs more explicit return values in C4::Bookseller.pm

[Srdjan]

From: root <root at kenza-VirtualBox>

Before, ModBookseller always returns undef. This patch modifies it in order to be more explicit.
Now it returns :
1 -> If a modification has been done
0E0 -> If the given id doesn't exist
undef -> If no id given

It also fix one of the tests which didn't pass before in t/db_dependent/Bookseller.t

To Test:
prove t/db_dependent/Bookseller.t
Bookseller.t .. 1/54
[Some warnings about uninitialized values]
t/db_dependent/Bookseller.t .. ok
All tests successful.
Files=1, Tests=54,  1 wallclock secs ( 0.03 usr  0.00 sys +  0.46 cusr  0.04 csys =  0.53 CPU)
Result: PASS
