Module updates not detected during initial deployment

[matt2e]

Steps:

• Start ftl dev with some modules
• While build and deploying modules, modify a module
• After initial modules are built and deployed, buildengine starts watching disk for updates
  Once initial modules are built and deployed, we have a mismatch between the deployed modules and what is on disk, but the module is not built & deployed again.

I think this will be more important once ftl dev is happening within VS Code, and when working on many modules at once (like PFI)

I've actually been experiencing this a lot in a project with many modules. Strangely doesn't happen in a project with just 1 module. Using 0.157.1
