Remote browser: Assert after adding a new remote

[foundry-markf]

I was browsing a package, and while the browser was open, I added a new remote to the local cache.
In the browser, I then went to choose a new recipe revision, but it always showed the same one regardless of what I chose.
I saw this in the console

Traceback (most recent call last):
  File "C:\dev\cruiz\src\cruiz\remote_browser\pages\packageidpage.py", line 338, in _on_back
    self._ui.stackedWidget.setCurrentWidget(self._ui.rrev)
  File "C:\dev\cruiz\src\cruiz\remote_browser\pages\reciperevisionpage.py", line 109, in showEvent
    self._ui.rrev_pkgref.setText(self._previous_pkgref)
  File "C:\dev\cruiz\src\cruiz\remote_browser\pages\page.py", line 93, in _previous_pkgref
    return self._previous_page.package_reference
  File "C:\dev\cruiz\src\cruiz\remote_browser\pages\packagereferencepage.py", line 119, in package_reference
    assert len(selection) == 1
AssertionError

Unsure if it's completely related to adding the new remote, but it was suspicious.
