fix: correctly set track_latest on MMR

[igamigo]

This PR introduces 2 fixes:

• (Closes debug assertions fail on integration tests #1402) When reconstructing the partial MMR, we were setting track_latest only based on whether there were client notes included in the block. This was not sufficient as track_latest is only meaningful if the leaf forms a single-leaf tree; in other situations the MMR code expects that the leaf will already be merged otherwise
• Fixes the code that adjusts the authentication path for a smaller forest. The main thing there was that we were keeping "in-bounds" nodes (from the same subtree) that were still part of the largest forest's path, not the current smaller one. Also introduces some regression tests for this

It also adds a couple make commands to run tests with test-dev (introduced in #1400) to run tests with debug assertions

We should probably look into adding this to main as well
