NethVoice: change extensions settings on migration instead of restart

[Stell0]

When freepbx container is started, some migrations are made on database to add proxy to extensions and trunks, configure webrtc and app extensions, add CTI permissions ...

Those are made by this script

Sometimes, some extension and trunks needs custom settings for codecs and to bypass proxy, but at every restart, those changes are overwritten. On trunk a workaround is to add "custom" to the name, to the extensions this isn't possible

Proposed solution

• only execute migration once

Test case 1:

• remove proxy from an extension
• update ns8-nethvoice
• proxy is added again
• remove the proxy from the extension
• restart the container
• proxy is no more added

Test case 2:

• enable / disable neth hotel from ns8 interface
• verify that hotel cti profile is added / removed
