all: remove theory import path references 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. Signed-off-by: Gerwin Klein <gerwin.klein@data61.csiro.au>
