report: gracefully handle XML report creation when no tests are run

Commit Message

Theodore Ts'o Dec. 31, 2018, 3:55 a.m. UTC

If no tests are run (because they have all been excluded) then make
sure we insert a valid timestamp into the XML file, and avoid printing
an error message when reading a non-existent test summary scratch
file.
