No picker should be needed when adding an email address in the Share by email option

Preconditions: Have the mail sending configured.

Steps to reproduce:

1. Log in as Admin or simple user
2. Click on Home page
3. Click on More Actions > Share by email
4. Type an email address in the "Send to" text box

Expected results: The email is added when the user types it in the text box.

Actual results: After the email is added in the text box the user has to click on "Select email..." for it to be saved. If he clicks on any other part of the page/screen before selecting it, the email vanishes from the text box and he has to type again and select.
