Bug description

When sharing a contact using "Share" in Android Contacts, the contacts phone number gets altered and adds +1 in front of their phone number by Signal. This seems to happen if the contact does not have a country code added to their phone number.

Steps to reproduce

• Go to your Android Contacts
• Pick a contact without a country code in their phone number
• Go to the More Options Menu (three dots)
• Tap 'Share' and select a Signal Contact
• Notice that the number has now changed format and a +1 has been added to the number.

Please note: This has been tested on Samsung S9 and a Nokia 7 as well, both up to date running the

Additionally, this bug may relate to #9439?

Actual result: The contacts number has been modified with a +1 in front. Causing the contact information to be invalid.
Expected result: The contact information should remain it's integrity when shared with Signal.

No source file or test is named in the report. First reproduce the Android Contacts > Share > Signal Contact flow with a number lacking a country code, then trace the sharing path and add coverage for preserving the original number rather than prepending +1.
