Fix for #73

[gizzmo]

To reproduce the error from #73 :

1. Open the import dialog.
2. Paste in a script. Not a PBS export text.
3. Notice the warning and Click continue.
4. Select the Rematch plugin.
5. Click the dropdown to select a key, (a Rematch team)
6. Error happens here.

In Rematch 5, iterating over the Rematch.savedTeams table will only return the methods on that table, and not the teams. Use :AllTeams() to iterate over all the teams.

This has not been tested on Rematch 4, but should work. But whos still running Rematch 4?
