Fix link in textual_region

[ZitaNemeckova]

Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1602095

Steps to Reproduce:
1.) Configure an appliance in region 0 as a remote appliance and an appliance in region 99 as the global appliance.
2.) Add an infrastructure provider to the remote appliance.
3.) View one of the provider's VM's in the global appliance's web UI.

Or a little hack in code:

--- a/app/helpers/textual_mixins/textual_region.rb
+++ b/app/helpers/textual_mixins/textual_region.rb
 module TextualMixins::TextualRegion
   def textual_region
-    return nil if @record.region_number == MiqRegion.my_region_number
+    #return nil if @record.region_number == MiqRegion.my_region_number
     h = {:label => _("Region")}
     reg = @record.miq_region
-    url = reg.remote_ui_url
+    url = "reg.remote_ui_url"

Click at Region and new window should open.

Before:

After:

@miq-bot add_label gaprindashvili/no, bug, blocker, wip

"return miqClickAndPop(this);" replaced by :external => true
