There is no way to undo evm_increaseTime

Expected Behavior

There is no way to undo evm_increaseTime. See "Current Behavior".

Current Behavior

• evm_increaseTime does not accept negative values, treats them as 0.
• evm_snapshot does not capture current BlockchainDouble.timeAdjustment , so...
• ... evm_revert does not undo effects of evm_increaseTime

Possible Solution

Either:

• add evm_setTime geth API.
• make evm_increaseTime to accept negative values.
• make evm_snapshot capture current BlockchainDouble.timeAdjustment and evm_revert to restore snapshot including time.

Steps to Reproduce (for bugs)

1. Start testrpc
2. Note current time
3. issue evm_snapshot
4. issue evm_increaseTime(365 * 86400)
5. issue evm_revert
6. observe current testrpc time, which is still 365 days from now in future.

Context

We make snapshots and do some test pieces inside these snapshots.
Calls to evm_increaseTime alters times outside of snapshots, affecting other tests.

This is addressed in PR #2. trufflesuite/ganache-cli-archive#390 is the testrpc related issue. This is a fairly debilitating bug.
