[native] Fix Entry deletion after creation

Summary:
Noticed that this.needsDeleteAfterCreation wasn't working as intended. The issue was that we were getting a concurrent_modification error because the prevText we were passing in for the delete did not match the text after creation. We were passing in the empty string since that is what this.props.entryInfo.text was prior to the CREATE_ENTRY_SUCCESS action being reduced.

To address this, this diff allows us to pass this.state.text in instead. This makes sure that we match what is in the keyserver MariaDB when we attempt the deletion.

Depends on D12262

Test Plan: Type an entry and then press the delete button. On web, confirm that it appears in the history, but it otherwise missing
