fix(pswap-distribution): add pool and liquidity of TBCD for benchmark

[i3ima]

Fixes #849. Not sure if my fix is correct as it's my first task after onboarding. Also I'm not sure if feature flags should be changed after this one because benchmarks are running with --features private-net,runtime-benchmarks,ready-to-test

Benches are run by 2 ways:

• As unit tests
• As benchmarking process

Please test both scenarios:
To run as unit test:

cargo test --features private-net,wip,ready-to-test,runtime-benchmarks

To run as benchmarks:

mkdir benches
cargo run --release --bin framenode --features private-net,runtime-benchmarks benchmark pallet --chain=local --execution=wasm --wasm-execution=compiled --pallet pswap-distribution --extrinsic "*" --steps 50 --repeat 20 --output  ./benches

All passes.

By the way I thought one of CIs runs such scenarios 🤷.

Unit tests - yes, benchmarks - no.
There is a separate benchmarking CI pocess that should be running manually before new release.

Good job! 🎉
