patches for #10459 and #10426...
a few small details escaped attention need to be fixed
😉
Removing unnecessary strings from Crowdin and improving typos.
Steps to verify the issue:
1. Open FreeCAD.
2. Switch to Std_ViewTop.
3. Click one of the curved arrows of the Navigation Cube.
4. Switch to the Draft WB.
5. Make sure Draft_SelectPlane is set to "Auto".
6. Start Draft_Arc and click 2 points (for the radius and the start angle).
7. Result: The displayed arc does not match the start angle or the current point.
Additonally:
* Removed the normal argument from `__init__`. The tracker does not work properly with just a normal. AFAICT there is no code that specifies this normal.
* Minor improvement to `getAngle`: Switched the vectors.
Presumably due to an copy/paste error, carbonCopy used to verify the
referenced object via `isExternalAllowed` (just like addExternal).
Now using `isCarbonCopyAllowed`, the resulting error message is the
expected one for wrong objects, not a generic one after the operation
failed.
The part behind the column represents the function name itself, not an
error message. So previously, an argument error looked like this:
("Give an object" is not the method name)
```
>>> obj.carbonCopy()
Traceback (most recent call last):
File "<input>", line 1, in <module>
TypeError: Give an object() takes at least 1 argument (0 given)
>>> obj.carbonCopy(123)
Traceback (most recent call last):
File "<input>", line 1, in <module>
TypeError: Give an object() argument 1 must be str, not int
```
While the format string also supports a text for the complete error message
(using a semicolon instead), I decided against this: Pythons standard text
is more precise than this:
(the type error here is not "Give an object")
```
>>> obj.carbonCopy()
Traceback (most recent call last):
File "<input>", line 1, in <module>
TypeError: Give an object
>>> obj.carbonCopy(123)
Traceback (most recent call last):
File "<input>", line 1, in <module>
TypeError: Give an object
```
