Regression: Build test.sh script is not properly running.

Regression: Build test.sh script is not properly running.

Three mistakes are introduced by the commit 362c7b9f6cd57421a18c0148fb6eb9bda165bcd2.
1) The error handling return status checks are against empty string and not "0".
2) The test.sh script is backported from the 0.7.x development branch and accidentally included projects not existing in this 0.6.x branch.
3) Accidental copy and paste mistake where print variable is being used as if it were a function.

Remove the failure=0 assignment.
The default of failure="" is what is needed.

The fl_path project is actually fll_path.

The variable print_line_first is supposed to be test_print_first.
