Missing milestone with an index of XYZ

[kwek20]

Bug description

When starting a node from LS files, i receive this error

Version

• Version: 1.8.5

Steps To reproduce the bug

1. Download LS files
2. Set your personal LS settings on a higher depth than those who created the LS files
3. Observe the node start up

Expected behaviour

Expected a small message or none at all

Actual behaviour

An error gets thrown because we try to make snapshots below our initial snapshot index.

How to solve

Dev side: This can be solved in a PR with a check for below initial MS index.

User side: this can be solved by waiting a bit, until your node has enough milestones to not reach below the LS files,or lower the --local-snapshots-depth parameter to below the used parameters of the snapshot generator
