Run with `set -e`

When I run with the bash -e option (stop at first command with a return code different from 0), the tests terminate at the first check because of this increment:

+ _smoke_success '2xx Response code'
+ REASON='2xx Response code'
+ _smoke_print_success '2xx Response code'
+ TEXT='2xx Response code'
+ echo '    [ OK ] 2xx Response code'
    [ OK ] 2xx Response code
+ ((  SMOKE_TESTS_RUN++  ))

I think this could be tweaked because incrementing 0 returns a 1 code which stops the script.

Good catch. I'm afraid smoke.sh isn't really set -e proof regardless as it relies on checking the exit code manually in various places as the moment.
