If selection in 'Extract Method' does not cover any node, extract the smallest covering expression.

Two comments.

1. We need also to change the Dart plugin for IntelliJ to not select
   the whole line when selection if empty. The whole line is almost
   never a good choice for Flutter.

2. This is not fully consistent with "Extract Lolal" where we give the
   client the list of possible expressions to extract and the user can
   then choose. Here we use just the smallest one. If we want to make
   it consistent, we will need to enchance the protocol and the plugin.
