Fix url params getting changed erroneously

[bhnord]

Bugs:

• URL params were getting changed: a param like ?param was getting changed to ?param= due to use in a javascript URLSearchParams object in env_tabs.tmpl.
• Some pages were not getting fed the correct data to render stage type filter.
• Some pages were rendering env_tabs but not providing the correct data to render the tabs
• Deploy history page was checking all rendered components and putting a limit on checked checkboxes, interfering with stage type filter

Fixes

• URL params are now modified with a custom parser in env_tabs.tmpl to not change url params formatting.
• Necessary pages are now fed correct data to render stage type filter.
• Pages that were previously rendering env_tabs.tmpl and not actually displaying any tabs (not providing the correct data) had the reference to env_tabs.tmpl removed.
• Changed deploy history page to only check components inside deploy history table
