[4.4.5]: Entry save fails and matrix block disappears when a conditional field is present on the entry

[mike-moreau]

What happened?

Description

When attempting to save a new entry, the first save fails and a matrix block is lost if the entry contains a conditional field.

Steps to reproduce

1. Create a section with a matrix field and a conditional text field. The matrix field should have min blocks 1 and max blocks 1.
2. Set the conditional text field to a setting that will cause it not to show. Should show matrix field only.
3. Attempt to save a new entry.
4. The first save will fail, but the second save will succeed.

Expected behavior

First save to succeed.

Actual behavior

Save fails and data loss on matrix block.
