weird routing when using sroute and ndr_rule

Description

More details of this problem can be found in #[3067] (The-OpenROAD-Project/OpenROAD#3067). Basically we seeing some weird behavior of the OpenROAD routing while using sroute command and ndr rules. During the connection from a cell to the power ring, there is a sudden change of wire width even though at the same layer. Also at some of the via cut, there is extra wire added which is way more than enough.
