#000 - Fix tests: Pluggable task new and edit tests.

These were rewritten in the way of tasks/exec/edit_html_spec.rb, where the template is
tested indirectly through the plugin task template at tasks/plugin/edit.html.erb, which
calls the task view service and render_pluggable_template, to test the real template.
This is closer to what happens in the app.
#000 - Fix tests: Send allow_auto_login param properly in specs.

Commit 79d5ba4348904785cfa55992a5298c2d23875ab0 changed how it is sent, from 'true'
and 'false' to '1' and '0'. This change corresponds to that.
