Add fill options for Phone and E-mail details

[jaapjansma]

With the fill details options I would expect that a phone number is added when no phone number with the location type and phone type exists.

When a phone number with that location type and phone type already exists I would expect that nothing changes. However the new phone number gets added and I end up with two phones of the same location type and phone type.

This PR enhances the settings for fill details for phone numbers. The same issue also exists with e-mail addresses and this PR also fixes it for the e-mail addresses.

Before

After

Below a screenshot with the changes applied to the settings screen:

And for e-mail

The changes are backwards compatible. Meaning that if someone had selected phone at the Fill details, the Fill Phone is set to If contact has not this phone number.

Comment

This PR also removes the phone_numeric field from the diff activity.

I have also added a fix for #85 which deals with the same issue but then for email. It was not really possible to create two PRs because the code would interfere with this PR.

I read through the code but have not tested it. Adding a unit test or two would help document the various cases and ensure they were handled as designed.

Hi @jaapjansma and @artfulrobot, we're currently compiling a 1.14-alpha what's the status of this PR? Does it need further work/clarification or would you both give a thumbs-up for the current state?

[jaapjansma]

@bjendres it has been a while ago since I wrote this PR. So I don't know exactly what the status is.

@bjendres I did an upgrade for a client which is using this functionality. So I checked this PR. And a rebase. Resolved merge conflicts. And also had a look at the feedback from @artfulrobot which was helpful and followed up his advice.

Can you have another look and possible merge this?
