Updated Usage page display to fix several issues. ...

- Moved mouse pointer instruction.
    - Made textual changes to "No. of plans by template"
    - The bar charts for  "No. users joined during last year" and
    "No. plans during last year" months are in ascending order. They were
    in descending order previously. Updated the count statistics methods
    in statistics_controller.rb.
    - The "No. plans by template" bar chart is now  replaced by a stacked bar chart
    as this is visually better for large data.
    - updated the by_template method in the create_or_update.rb with code from @xsrust.
    This now aggregates template counts for a month correctly.

    Fix for issue #1679.

Restyled Usage page: ...

- The 'No. of plans by template" section restyled
 - Added instruction to 'No. of plans by template'
 - Added a message for 'No. of plans by template' chart if
 no data available for a chosen time period.

The "No. plans by template" statistics and visualisation changes: ...

(1) The headers for the CSV for the Number of Plans by Template
             - the date column have dates in the format  'Jan 2018'
             - the template headers now display the Title of the templates
             - the Date and Count headers are capitalized.

        (2) The chart has been re-styled.
            The aspect ratio (width/height) of image is now dynamically
            set according to the selection of the month range.

        (3) Fixed broken rspec tests and rubocop errors/warnings.
