Text Template node creates an input socket for each time a variable is referenced.

[parzival418]

Text Template node creates an input socket for each time a variable is referenced.

Steps to repro:
Create a Text Template node.
Select the Text Template node.
Within the Text Editor field, create a variable by using the {{}} notation.
Observe the creation of an Input Socket with that variable name.
While in the Text Editor, type the same variable name using {{}} notation. (e.g. if you put {{test}} in step 3, write {{test}} again)
Observe the creation of a SECOND Input Socket with the same variable name.

Expected Results:
Duplicate uses of a variable in the Text Field reference the same variable Input Socket and does not create new sockets.
