PhdcScrubber replaces Road with suburb name if not comma separated

[ColinAnthony]

Road name is replaced with suburb name, unless there is a comma after the suburb for some cases where there are multiple matches to the road name:

This is not completely consistent as main road claremont western cape results in the error, but not main road observatory western cape

Error example:

Peak rd vredehoek western cape or Peak rd, vredehoek western cape gives
