[throuz]

Describe the bug
If Format On Save is ticked in the VS Ccode settings, the solidity file will ignore the changed part when saving and save it as an unmodified version.

To Reproduce
Steps to reproduce the behavior:

1. Ticked Format On Save in the VS Ccode settings
2. Make changes to the solidity file
3. Use cmd + s to save the solidity file
4. Will find that the changes are missing

Expected behavior
Should be able to save changes.

Hyperledger Solang version
v0.3.3

Additional context
Manual format and manual save will not have this problem.
