FIX-2205 Fix copy log curve bugs

Fixes

This pull request fixes #2205 and #2191

Description

Fixed these bugs:

• Error when using "CopyToServer" if you include the indexCurve.
• LogCurveInfo properties are not copied if the target curve already exists.
• LogCurveInfo properties are not copied if using "Copy with range to server", and the curve is outside the selected range.

New behavior:

• If using "CopyToServer" with the indexCurve, it won't attempt to delete it.
• The LogCurveInfo object is always copied for selected curves, even if the target LogCurveInfo object already exists, and even if it's not within the specified range.
• When copying the index curve, properties other than uid and mnemonic in the LogCurveinfo object will be copied, even if the names of the index curves does not match. The uid and mnemonic of index curves can not be changed for a log.

Note for the reviewer:
The removed Assert in the test was removed as for this test there are no "existing" mnemonics to copy. Before I ensured that the target log had the correct mnemonic and uid of the indexCurve LogCurveInfo object, the worker added it as an existing mnemonic. As we do not have any existing mnemonics, there is one less call to UpdateInStore.
