cmd: defer stating model info until necessary (#5248)

This commit changes the 'ollama run' command to defer fetching model
information until it really needs it. That is, when in interactive mode.

It also removes one such case where the model information is fetch in
duplicate, just before calling generateInteractive and then again, first
thing, in generateInteractive.

This positively impacts the performance of the command:
