Fix bugreport rename in API workflow

In the current implementation of API flow of bugreport, renaming bugreports
works fine but it changes the entire name. In legacy flow, the user is only
able to rename the suffix of the file. The prefix of the name
(bugreport-deviceName-buildID) remains unchanged. Also, wifi and
telephony bugreports have the type of the bugreport specified explicitly
in the name.

Fix Shell's rename implementation to follow legacy logic. Also stop setting
name property in the API flow since it's a functional no-op anyway, and we
want all communications to dumpstate be through the API when possible.

No need to call trackInfoWithId() for remote bugreports as Shell does not
process any notification related to it.

Bug: 123617758
Test: * Take interactive bugreport, rename and save. (work as expected)
Test: Corner case:
      * Take interactive bugreport, rename and save.
      * Click on the progress notification again and keep the edit box
        open.
      * Wait for bugreport to finish, filename edit box would be disabled
        and autofilled with last saved rename. You will still be able to
        edit title and summary. (works as expected)
