Bug: Multiple master programmes confuse frontend

[MichaelAkvo]

What were you doing?

As an admin, I created a new master project in the test environment https://rsr.akvotest.org

• Create a new, standalone project
• Add a new project hierarchy and make it a master program
• Create a contributing project for the new program
  
• Create a new program
  
• Open the master programme's hierarchy
  

What should've happened?

Not entirely sure but at the moment only the project is being shown in the hierarchy and not the child program.

My environment

Browser: Firefox 107.0 (64-bit)

Additional context

The code selects the master program in an unstable manner:

akvo-rsr/akvo/rsr/spa/app/modules/projects/projects.jsx

Line 241 in 6d9db83

const masterProgram = userRdr.programs.find(it => it.isMasterProgram)
