bug fix: version not retrieved on weekly jobs
a first fix had been done
but the version was retrieved 2 times with the regex
this patch removes the second regex and re-use get_version
the associated unit tests has been removed because even
if the build_tag is badly formated, it will not prevent
the results to be pushed with version = unknown
