SUMMARY
***
Remote slewing and plate-solving target update problem:

when slewing with remote access(tested with kstars and stellarium as remote clients),
there occurred 2 problems:

- Name of target is not displayed in the Capture view.
- target coords are not forwarded to Align, so plate solving gives
 not the delta from position to desired position but instead the delta
 between park position and slew position, so 'slew to target' does not work.
***

 This bug has been introduced in version 3.5.6.


STEPS TO REPRODUCE

1. run kstars/ekos (3.6.x) and simulator telescope and ccd, GSC installed for plate solving simulation.
  - run ekos and hit 'start'.
  - telescope mount in park position.
2. unpark the mount.
3. on another machine start kstars and connect via Tools/Devices/Device Manager...
4.  on client machine slew the telescope to M81
   - either by selecting it in the map and rightclick and select in context menu 
       'Telescope Simulator/Slew'.
   - or by clicking ctlr-F and finding M81 and clicking "Details..." and then 
       "Center in Telescope".
5. Telescope as expected points to M81.

See logs at the end of this report!

OBSERVED RESULT
- In Ekos/Capture view the text box labeled 'Target:' is _not_ updated.
- in the 'Align' tab when clicking 'Capture&Solve' with the 'Solver Action' set to 'sync':
    the solver finds the position but gives a wrong error like: 
    "673084 arcsec. RA:541515 DE:-399754".


EXPECTED RESULT
- in the Capture view the 'Target' text box shows "M_81".
- 'Capture&Solve' should gives an error in the range of <60 arcsec.

when doing the above-mentioned steps from the local kstars map, everything
works fine as described in EXPECTED RESULT.

PROPOSED FIX
I have provided a merge request that produces the expected result:

SOFTWARE/OS VERSIONS
Tested on Ubuntu/amd64 and Raspberry arm64.
This bug does not seem to be a platform-specific problem.
