Make load handle free filename too

[kawaz]

I want to load my_helper.sh
But bats add .bash to forcibly my filename, and then the test failed with error.

Problem

$ cd test/fixtures/bats/
$ echo 'help_me() { true; }' > my_helper.sh
$ HELPER_NAME=my_helper.sh bats load.bats
bats: /path/to/bats/my_helper.sh.bash does not exist

$ # It also fails
$ HELPER_NAME=test_helper.bash bats load.bats
bats: /path/to/bats/test_helper.bash.bash does not exist

Solved

I solved the problem.
If the file exists, bats use it.

$ cd test/fixtures/bats/
$ echo 'help_me() { true; }' > my_helper.sh
$ HELPER_NAME=my_helper.sh bats load.bats

$ HELPER_NAME=test_helper.bash bats load.bats
