Fix database diagnostics tab

This is to fix the following two problems:
1. Traceback when accessing the diagnostics -> database tab:

Error caught: [NoMethodError] undefined method `display_name' for nil:NilClass
vmdb/app/views/layouts/_edit_log_depot_settings.html.erb:17

2. DB depot selection not working. This was caused by @prev_uri_prefix
being erroneously overwritten by log_depot_get_form_vars() method.

Reset value of index if chart is not available.

- Added line of code to reset value of index in @perf_options to fix an issue([] for nil:NilClass error), if user has zoomed in on one of the charts and then changed options such as group by from the options box on the screen and the returning result didn't include the chart user was zoomed in on. With this change user will be presented with all the zoomed out available charts.
- Moved setting of chart_layout variable outside of the if block as perf_gen_chart_layout method might set @perf_options[:index] to nil in case the zoomed in chart is not present for selected options on screen.
