fix(web): add Retrofit2SyncCall.execute to BakeService (#1879)

* refactor(web): use constructor injection in BakeService

to pave the way for more testing

* test(web): demonstrate behavior of BakeService

and how it's not using RoscoService / retrofit2 properly

* fix(web): add Retrofit2SyncCall.execute to BakeService

since (as of #1866) RoscoService uses retrofit2.

+    // cloudProvider) to match (my preference), or leave it returning a Map and
+    // convert in BakeService.bakeOptions.  The corresponding rosco code is at
