* The perl-uri-escape package duplicates perl-uri
The Perl URI::Escape module is in the Perl URI package so the Spack
perl-uri-escape package is a duplicate of the perl-uri package. This PR
does the following:
- replace `depends_on('perl-uri-escape')` with `depends_on('perl-uri')`
in packages that dependend on perl-uri-escape
- add the version from perl-uri-escape to perl-uri
- remove the unneeded dependency from perl-uri
- remove the perl-uri-escape package
* Reinstated perl-test-needs dependency
Put the perl-test-needs dependency for perl-uri back in but set it to
type='test'.
* For tests to succeed the type must be ('build', 'test')
