[Applet] Fix connecting with a password
Summary:
I could have sworn that I tested this during the initial ExpandableListItem port, but
the code change required to fix it suggests that I either did not, or was smoking crack
at the time. Sorry about the breakage.
Test Plan:
Entering a password in the password field and hit return; password is sent and it tries
to connect
