Sender verification should trim spaces

[ethanfrey]

Using the native wallet, I attempted to send to "coral1z2y9wl48uj23veyypjp0sud997ukdqmhpa5cgd ", but the send button was disabled. I deleted the trailing space and it all worked.

This is a minor annoyance with cut and paste, and I have had this in many websites when entering my email, which is rejected if there are trailing spaces. Still, auto-trimming whitespace at the beginning and end of the address before validating (and submitting) it would be a nice UX boost. I guess it would be nice to add that as a helper to the logic package, so this is done consistently between all addresses in all apps.
