Rename LocationBarModelTest in junit to LocationBarModelUnitTest

Before this change there are two files named LocationBarModelTest.java
Touching either of these files triggers a presubmit warning:

WARNING: multiple definitions of org.ch.c.b.toolbar.LocationBarModelTest:
  _/src/c/a/javatests/src/org/ch/c/b/toolbar/LocationBarModelTest.java
  _/src/c/a/junit/src/org/ch/c/b/toolbar/LocationBarModelTest.java

Now the file in junit is renamed to LocationBarModelUnitTest.java
