bitbake: toaster: widgets ToasterTable Catch template rendering exceptions

If a cell template rendering causes an exception catch it and carry on,
this at least allows the table to show the rest of the data if nothing
else. Also improve the error logging so that it's possible what the
offending template snippet was.
