Remove unnecesary variable

This will be removed until we figure out in what scenario we should display the overview message.

app/views/projects/cycle_analytics/show.html.haml

 - @no_container = true
 - @cycle_analytics_not_set_up = false
 - page_title "Cycle Analytics"
+- content_for :page_specific_javascripts do
+  = page_specific_javascript_tag("cycle_analytics/cycle_analytics_bundle.js")
 = render "projects/pipelines/head"
-- if @cycle_analytics_not_set_up
-  = render partial: "overview"
-- else
-  - content_for :page_specific_javascripts do
-    = page_specific_javascript_tag("cycle_analytics/cycle_analytics_bundle.js")
 #cycle-analytics{ class: container_class, "v-cloak" => "true", data: { request_path: project_cycle_analytics_path(@project) } }
   .bordered-box.landing.content-block{"v-if" => "!isOverviewDialogDismissed"}
     = icon("times", class: "dismiss-icon", "@click" => "dismissOverviewDialog()")
