[BUGFIX] Fix initialization of TOTP info modal

The TOTP info modal displays the OTP auth url
along with a description. This content however
is added to the modal body by a callback. To
prevent the "modal content empty" warning
from being shown, the modal is now initialized
with an empty string as content.
