bug(core): when calling km_core_state_get_actions, persist_options contains unexpected values

[sgschantz]

Describe the bug

After processing a key with Keyman Core, calling km_core_state_get_actions does not return a valid key value pair in the persist_options field as expected.

Reproduce the bug

1. use the Armenian Mnemonic keyboard
2. type[alt-v]
3. expected: "√"
4. type[w]
5. expected: "" -- ("√" is deleted)

This should toggle the option 'option_ligature_ew' from a value of 0 (zero) to 1 (one)

However, calling the API returns invalid values, so they will not be persisted correctly on the platform and may cause the app to crash while attempting to parse them.

Helps if the unit test is actually attached. Unit test, once attached, fails. So I am starting there.
