Problem
There could be cases where a project name (Pname) is used as a project key (Pkey) of a separate project.

When using the autocomplete on issue navigator, the JQL string get filled with the Pname.

Steps to reproduce
For example, if we have two projects (Pname) (Pkey):

1. SUPPORT (ABCSUPPORT)
2. Support Template (SUPPORT)

Selecting the first project would create the JQL as:

project = SUPPORT

Selecting the second project would create the JQL as:

project = "Support Template"

Because JQL prioritizes project key, the first JQL returns results from the second project.

Proposal
JQL autocomplete for project should select "Pkey" instead of "Pname" when filling up the JQL. This would make it aligned with JQL searches which prioritizes Pkey.

When user selects the first project, the JQL should be filled up as:

project = ABCSUPPORT
