Bug Description

In master branch, the error "Mismatch between hierarchical labels and pin sheets" is not issued anymore. In stable versions (5.1.2 and 5.1.4) still works.

To reproduce it:
1)create a new hierarchical sheet
2) add a hier. pin with "Place hierarchical pin in sheet"
3) inside the child sheet place a resistor and connect it to two hierarchical labels with a name different from the one in the parent sheet block (call them both "a")
4) Run the ERC: No error is issued.

(attached file: the project with this issue)

Running ERC on the same file using stable version you get 3 errors for "Mismatch between hierarchical labels": correct. (also two more errors that are not correct, subject for another minor bug report)

Note: May be related to Bug #1781725, but there the "Mismatch between..." error is reported to work correctly.
