The commit reverts source root order respect for import statements thus
reopening PY-28321. The reason is that until pkg_resources and pkgutil
namespace packages are not implemented (see PY-16688, PY-23087) the
original fix leads to false positives in projects relying on this
functionality.

As soon as namespace packages support via pkg_resources and pkgutil will
 be implemented the change should be reverted back to close PY-28321.

These actions can cause different hard-to-debug issues in UndoManager.
One of the known issues is mishandling of transparent actions.

Redo action is being registered only at the end of command.
If the document was modified in a transparent command, redo action will not
be registered until when next (completely unrelated) command is finished.

As a result, it causes "Can't Undo" errors, if that other command was
not supposed to be undoable (and was performed on workspace.xml or
some lightweight temporal file)

We can check is framework is installed for local sdk, but not for
remote.

So, fo local we call ``installFrameworkIfNeeded`` with
forceInstall and for remote is checks if framework is installed
by itself.

``installFrameworkIfNeeded`` shows modal window while
checking/installing framework (both local and remote) and then
runs callback to generate project and do further actions

Done for Flask and Django.

This is not supported for plugin for now
