Add page links doesn't contain selected namespace

Description of problem:

When a user selects a namespace and goto the add page, some add page links do not contain the selected namespace. Open one of this links in a new tab redirects the user to the latest saved namespace instead of the current selection.

This could be changed by another browser tab or user (shared account) in the meantime. The additional redirect (history push) is also not required and looks not ideal.

This happen at least for the following links:

• All Developer Catalog links (All services, Database, Operator Backed, Helm Chart, Event source)
• All Git Repository links (From Git, From Devfile, From Dockerfile)
• Container images
• Samples
• Serverless Channel
• But NOT Pipelines
• From local machine Upload Jar file but NOT import YAML

Prerequisites (if any, like setup, operators/versions):

None

Steps to Reproduce

1. Open developer perspective in two tabs
2. Open in both tabs the add page and select "All projects"
3. Tab 1: Create or select a namespace (namespace-a)
4. Tab 2: Create or select another namespace (namespace-b)
5. Tab 1: Click "Import from git"

Actual results:

You have been automatically switched from namespace-a to namespace-b

Expected results:

The already selected namespace (which is part of the URL) is used when open the import from git page.

Reproducibility (Always/Intermittent/Only Once):

Always
