Skip error handling: my $e = ERR_get_error() = 0

Manual:ERR_get_error(3): The error code, or 0 if there is no error in the queue.

repeat {} executes the block once regardless of the conditional, so non-errors will get output

Heres two examples of the same test being run twice in a row that this pr appears to have fixed:

localhost:~/perl6/zef$ perl6 -Ilib  t/zef-getter.t
1..3
    ok 1 - Created getter
    ok 2 - no plugins loaded
err code: 0
Segmentation fault
localhost:~/perl6/zef$ perl6 -Ilib  t/zef-getter.t
1..3
    ok 1 - Created getter
    ok 2 - no plugins loaded
err code: 0
error:00000000:lib(0):func(0):reason(0)
    ok 3 - Used default .get method
    ok 4 - Modules were fetched
    ok 5 - deleted test modules
    1..5
