The point is to have visibility on the development of the owl2 features.
This commit reintroduces some tests keeping them skipped in order to fulfill that purpose.
There still are some missing tests though.
We add some test for the t-on directive.
For making them pass, it was necessary to change the code produced by
compileTForeach: the const declaration is not done by using generateId
and there was some conflict with the variable names produced in
captureExpression. Consequently, many snapshots had to be changed.
Code prettification has been done too.
