Please remove the italicized help prompts before submitting or merging

Provide a general summary of your changes in the Title above

Pull requests without a rationale and clear improvement may be closed
immediately.

Please provide clear motivation for your patch and explain how it improves
Dash Core user experience or Dash Core developer experience
significantly:

  • Any test improvements or new tests that improve coverage are always welcome.
  • All other changes should have accompanying unit tests (see src/test/) or
    functional tests (see test/). Contributors should note which tests cover
    modified code. If no tests exist for a region of modified code, new tests
    should accompany the change.
  • Bug fixes are most welcome when they come with steps to reproduce or an
    explanation of the potential issue as well as reasoning for the way the bug
    was fixed.
  • Features are welcome, but might be rejected due to design or scope issues.
    If a feature is based on a lot of dependencies, contributors should first
    consider building the system outside of Dash Core, if possible.

Issue being fixed or feature implemented

  • Why is this change required? What problem does it solve?
  • If it fixes an open issue, please link to the issue here.

## What was done?
ClientModel returns now a pair: MNList and CBlockIndex; so, we always
know the which one has been used even if current chain is switched.

## How Has This Been Tested?
Run on my localhost from `c034ff0c2606142ba3e8894bc74f693b87374e5c` -
aborted with backtrace like above.
With both of commit - no assert more.

## Issue being fixed or feature implemented
Now that we have ChainLock sigs in coinbase `VerifyDB()` have to process
them. It works most of the time because usually we simply read
contributions from quorum db
https://github.com/dashpay/dash/blob/develop/src/llmq/quorums.cpp#L385.
However, sometimes these contributions aren't available so we try to
re-build them
https://github.com/dashpay/dash/blob/develop/src/llmq/quorums.cpp#L388.
But by the time we call `VerifyDB()` bls worker threads aren't started
yet, so we keep pushing jobs into worker's queue but it can't do
anything and it halts everything.

## What was done?
Start LLMQContext early. Alternative solution could be moving bls worker
