fix(windows): lower case filenames for projects 🍒

Turns out there are more things we need to clean out if we run
into an error condition in the c'tor. Easiest is to call the
destroy method.

filename conflicts in symbol servers.

fix(android/engine): Make it easier to test keyboard updates

Co-authored-by: Marc Durdin <marc@durdin.net>

While release builds need to build a specific commit hash, test builds
should always build the HEAD of the branch. This stops multiple merges
and/or pushes generating multiple test builds in the queue.

- set keyboard options in a call to `km_kbp_state_options_update`
  separate from setting the environment options
- output status value if method fails
- if any of the methods fails we now return NULL
- split setting the options in multiple methods

Fixes #7717.
