The benefit of the wpx method is not worth the maintenance effort.
There are still a few instances of wpx left in AInvs, which will have
to be fixed later.
We are keeping the wps method from the same file (WPEx.thy), because
that is used more widely and does not break with Isabelle2021-1

In Isabelle2020, when isabelle jedit is started without a session
context, e.g. `isabelle jedit -l ASpec`, theory imports with path
references cause the isabelle process to hang.
Since sessions now declare directories, Isabelle can find those files
without path reference and we therefore remove all such path references
from import statements. With this, `jedit` and `build` should work with
and without explicit session context as before.
