Fix assertFieldContains() calls undefined method (#221)
Fix assertFieldContains() calls undefined method (#221)

Steps:
Invoke FlexibleContext::assertFieldContains with valid arguments.

Expected Behavior:
The method should assert that the specified field contains the specified value.

Actual Behavior:
The method throws an error stating that an undefined method "injectStoredValues" was called.

Cause:
The "injectStoredValues" method exists on the StoreContext class, but "assertFieldContains" is calling it on "this".

Fix:
Update the "assertFieldContains" to call "injectStoredValues" on "this->storeContext".
