Title: pool_solvable2str: improve output when version is not defined

Do not add the '-' char separating solvable's name from its version when
this attribute is not set.

Prior to this patch a pattern without a solvable would produce the
following string: 'pattern:Crowbar_Admin-.noarch'. With this patch the output is
'pattern:Crowbar_Admin.noarch'.
