## Issue being fixed or feature implemented
Trivial bug: `keypoolrefill` internally updates the status of the
progress bar each second.
```
m_storage.UpdateProgress(strMsg, static_cast<int>(dProgress));
```
However it can happen that one second is not enough time to make
significant progress and
`static_cast<int>(dProgress) = 0`.
Calling the function with `0` as progress opens a new progress bar and
this led to problems like #5730
## What was done?
trivially make sure to update the progress only if the parameter is >0
## How Has This Been Tested?
rpc does not spam anymore
