title: tSQLt.RunAll returns 0 test cases but tSQLt.Run <schema name> works
body: <p>I previously had an install of tSQLt on my database, along with some tests.  I used the tSQLt.Uninstall to remove it and then deleted all the tests and the schema's they were in.</p>
  
  <p>I have reinstalled tSQLt and created a new schema and created a bunch of new test stored procs.  When I perform a tSQLt.RunAll I get;</p>
  
  <pre><code>+----------------------+
  |Test Execution Summary|
  +----------------------+
  
  |No|Test Case Name|Result|
  +--+--------------+------+
  -----------------------------------------------------------------------------
  Test Case Summary: 0 test case(s) executed, 0 succeeded, 0 failed, 0 errored.
  -----------------------------------------------------------------------------
  </code></pre>
  
  <p>When I run tSQLt.Run Test_DWH_UnitTests I get results.</p>
  
  <p>The tSQLt.RunAll worked against the previous install.</p>
  
  <p>Any help would be very much appreciated. - Many thanks</p>
