#### Description <!-- Describe your changes in detail --> This PR fixes a bug in pseudo-variables related to "From" and "To" headers and changing the `Display Name` through `$tu/$fu/$fn/$tn`.
According to standard the URI must be enclosed in <> if a `Display Name` is given, but it may or may NOT if no display name is present.
So, if one tries to modify the `from`/`to` header with an initial empty display name and URI that is NOT enclosed in <>, it yields an invalid message.
This PR makes sure that if URI was not enclosed in <> and display name is modified, that will wrap URI in <>. You can view, comment on, or merge this pull request online at:
