Query Builder merge don't translate names

[Nisgrak]

Describe the bug
Using query builder with onConflict and merge it doesn't use the naming convention to translate the props

Stack trace

insert into `issues_clients` (`added_time`, `anomaly_id`, `id_issues`, `id_issues_clients`, `id`, `provcode`, `solved_time`, `status`, `ticket_pending`, 
`updateAt`) values (1628665711, 'XXX', 45129, NULL, 'XXX', 'XXX', 0, 0, 0, '2021-09-06 12:10:58.086') on duplicate key update `status` = VALUES(status),`solvedTime` = 0 - (conn=512988, no: 1054, SQLState: 42S22) Unknown column 'solvedTime' in 'field list'
sql: insert into `issues_clients` (`added_time`, `anomaly_id`, `id_issues`, `id_issues_clients`, `id`, `provcode`, `solved_time`, `status`, `ticket_pending`, 
`updateAt`) values (1628665711, 'XXX', 45129, NULL, 'XXX', 'XXX', 0, 0, 0, '2021-09-06 12:10:58.086') on duplicate key update `status` = VALUES(status),`solvedTime` = 0  - parameters:[]

To Reproduce
Steps to reproduce the behavior:

1. Create querybuilder insert
2. Use insert, onConflict and merge
3. Pass an object to merge with fields to update on duplicate

Expected behavior
The on conflict updates of sql need to have solved_time not solvedTime

Additional context
The entity has solvedTime prop, and in the db has solved_time, work with other methods.

I'm using this object in merge

{
    "solvedTime": 0
}
