[Bug]: Unable to create blockchain if previous attempt failed

[RodrigoVillar]

Describe the bug

When using avalanche blockchain create, if the commands fails, then running the command again with the same blockchain name is not possible because the corresponding folder in .avalanche-cli/subnets already exists, but is malformed.

To Reproduce

1. Via the README, install Avalanche-CLI using the following:

curl -sSfL https://raw.githubusercontent.com/ava-labs/avalanche-cli/main/scripts/install.sh | sh -s

2. Call avalanche blockchain create morpheusvm
3. For the genesis, use an empty JSON file
4. For the VM binary, use the MorpheusVM binary
5. After the prior two steps, you should get an error relating to a field in the genesis not being specified. This is fine.
6. Call avalanche blockchain create morpheusvm. This should result in an error

Expected behavior

I expected for the CLI to clean up the malformed folder, thus allowing me to execute the command again.

Operating System

macOS 14.5

Additional context
To create the binary for MorpheusVM, go to the HyperSDK repo and run the following in examples/morpheusvm:

go build -o ./build/morpheusvm ./cmd/morpheusvm

for more context, the particular error message is subnet %s has inconsistent configuration. there is no %s file present on directory %s. please backup any file and then remove the subnet, has can happen if the subnet directory was created but by failure the sidecar not.

working on a fix so automatically clean up is made by CLI
