Use v1 cover sumAssured as it is (already in wei)

[mixplore]

Context

The cover migrate transaction for a v1 cover got reverted with reason string SafeCast: value doesn't fit in 96 bits on the amount param.

Changes proposed in this pull request

I noticed that the sumAssured value of a v1 cover (at runtime) was already in wei (had 18 0s) so there was no need to convert it further. The change in this PR removes that conversion.

Test plan

I've only tested it locally, using the deploy script and calling the migrate contract method from the FE app. With this change, the v1 cover gets migrated successfully.
