log number parsing errors
value
- we are getting an increasing number of bug reports from international users for whom valid phone numbers are failing to parse, which we suspect has something to do with how plus signs are encoded from their mobile keyboards. (see #426 (closed))
- usually the first step in resolving these issues is looking at the user input and (invariably) creating the channel for the user
- here, we make that process faster by logging invalid phone numbers as errors, so we can inspect logs to find correct phone numbers and more quickly create the channel for them
