Fix errors related to dynamic precedences

[gmlarumbe]

Remove some dynamic precedences from the grammar to try to fix most errors related to nested indexes.

Commit e975694 might add breaking changes to queries related to select inside method_call. The following query should no longer be valid:

 (method_call
  (select "." (simple_identifier))

@clason , there might be breaking changes in Nvim queries

Thanks for the heads-up! Doesn't look like it, luckily.

If you want to look over the queries and check if any non-breaking changes are needed (to make use of new features), that would of course be appreciated ;)
