Show pending popover menu when password is enabled by default

Show pending popover menu when password is enabled by default

When "Enforce password protection" is enabled in the sharing settings a
popover menu is shown to set a password before the share is created. On
the other hand, when "Always ask for a password" was enabled in the
sharing settings and a new link share was created the share was
immediately created with a default password; the user was not able to
specify a password (nor create the share without password).

The component template already provided the needed elements to also ask
for the password without enforcing it, but the popover menu was not
shown due to "enableLinkPasswordByDefault" being missing in "if"
conditions.
