[FIX] One way or reading emails, only html.
The reason for this is that having two jobs reading the emails after each other,
makes on of the jobs useless, since the mail server marks the emails after
one of this jobs are fired.
E.x.: ``./artisan email:read --html_enable=true --email_search="UNSEEN"`` will actually
cause all the unseen emails to be marked as 'seen', which we definatelly don't want to,
since it makes ``./artisan email:read --email_search="UNSEEN"`` useless, since this
command won't be able to read any of the emails.
For this reason only one general command to read the emails, and that with html enabled.

Revert keyword check as well, no need to check by ``--html_enable`` option.
