Subject: [PATCH] Fix bad autocomplete of partially written node paths when
 using syntactic sugar notation ($)

If you had a tree like Node2D->Sprite->Camera2D and you write a
code like $Node2D/Spr and chose the autocompletion sugested
Node2D/Sprite, the resulting string was $Node2D/Node2D/Sprite
instead $Node2D/Sprite. If you chose Node2D/Sprite/Camera2D, then
you ended with $Node2D/Node2D/Sprite/Camera2D.

Fix #15813.

(cherry picked from commit 95f186b62184c846571c7278842ac4923f461d5a)
