NethVoice: If i set an extension as an object's destination using Visual Plan, the extension settings are reset to default.

[fabbri-marco]

Description:
If I modify an extension's settings in "Applications -> Extensions", and then I go to Visual Plan to set that same extension as a destination for a condition and save, the previously modified advanced settings are removed and the extension configuration reverts to default.

Steps to reproduce

• Access the FreePBX advanced settings.
• Go to Applications -> Extensions and edit an extension.
• Modify a parameter (for example, the Optional Destinations for "No Answer").
• Modify an inbound route via Visual Plan assigning the same extension as a destination for an object or condition.

Expected behavior
When I set an extension as an inbound route destination via Visual Plan, the settings previously modified in the FreePBX 'Advanced' tab must NOT be reset to default.

Actual behavior:
Currently, settings modified in the FreePBX advanced tab are being reset and reverted to default after setting the extension as a destination via VisualPlan."
