Issue with Edit Feature in-place for Split with Lines

[askaribaloch]

What is the bug or the crash?

• split with line feature when edit in place is true gives this error for primary key present in database

`Could not commit changes to layer roads_v5

Errors: ERROR: 4 feature(s) not added.

Provider errors:
PostGIS error while adding features: ERROR: duplicate key value violates unique constraint "pak_roads_v5_pkey"
DETAIL: Key (id)=(1311202) already exists.
`

• tool must produce new primary key id's for in place feature editing in postgis or database layers where primary key is present

Additional context

tool unable to produce new id for split feature tool when used on postgis line layer

[askaribaloch]

please review above behaviour using postgis database layer with edit feature in place enabled for split with lines

[askaribaloch]

I have reported the issue with the PostGIS layer, which is a line feature with an ID field that has a primary key enabled and uses a sequence for the next value.
