Use weak scrypt N, P parameters everywhere

[manoranjith]

Description

• Currently weak scrypt parameters are used in tests within session package and for generating test data, while standard scrypt parameters are used everywhere else (integration tests in other packages, CLI & TUI apps).

• This causes the open session action in these tests and apps to be slower. Since, we use perun-node only in test environments with no real funds, use weak scrypt parameters everywhere to make the test and apps faster.
