Test HH2 alpha with multi-chain EDR 2

[michalbrabec]

Describe the issue

Repeat the following steps for each repository:

1. Clone the following repositories (one-by-one)
2. Update the Hardhat used in the repositories to the latest stable Hardhat 2 (2.26.3)
3. Test the repository functionality
   • Build the repository (pnpm build)
   • Run the existing tests (pnpm hardhat test)
   • Note the results
4. Clean the repository (remove all caches, artefacts and results)
5. Update Hardhat in the repository to the version 2.27.1-alpha.1
   • Build the repository (pnpm build)
   • Run the existing tests (pnpm hardhat test)
   • Note the results
6. Compare the results to the outcome of the test with stable version
   • Document findings in the associated task
   • File identified issues as bugs

• Test in https://github.com/Uniswap/v3-core
• Test in https://github.com/ProjectOpenSea/seaport/ (1 test failure due to accessing HH VM private properties)
  Test in https://github.com/neptune-mutual-blue/protocol (same 29 failures in EJS and EDR mode)

Separately:

• Test parallel mode in a sample project (run tests on the hardhat sample project in parallel using the Mocha parallel mode)

Running on uniswap v3 core works fine, just need to remove the snapshots directory when running tests across different versions.

Tests passing on seaport both o 2.26.3 and alpha
