[BUG] Some event location mappings are incorrect.

[sandeep-ps]

Describe the bug
Using the string "Urbana" results in defaulting to the Urbana downtown area.

To Reproduce
Steps to reproduce the behavior:

1. Go to events with abbreviated locations (e.g., Loomis)
2. An example event - https://api-dev.rokwire.illinois.edu/manager-events/event/detail/643a84430c9345a9491a22fd - location is "Family Resource Center 1834-A"
3. See that the location is in the downtown Urbana area, even though the actual location is somewhere else. (see screenshot below)
4. It's not difficult to find other similar events (once this expires).

Expected behavior
Please check if using the "Champaign-Urbana" string instead of "Urbana" can reduce the number of such incorrect mappings.

Screenshots
If applicable, add screenshots to help explain your problem.
