[#596][#597] Fix decodeIntIfPresent and related tests

[tjwio]

Resolves #596 and #597

Short description 📝

Some of our Xcode projects were failing to be decoded due to proxyType being encoded as an Int when decodeIntIfPresent only tries to decode as String/Bool.

Solution 📦

• Fix decodeIntIfPresent to try to decode UInt if decoding as String/Bool fails.
• Fix _____BuildPhaseTests to properly check failure cases now that decodeIntIfPresent doesn't wrongly throw when trying to decode encoded ints.

Implementation 👩‍💻👨‍💻

Detail in a checklist the steps that you took to implement the PR.

• Fix `decodeIntIfPresent
• Fix tests
• Run tests
• Test in failing project
