Package destroyed before use in environments when `recreate=True`

[raffienficiaud]

Issue

When specifying several environments from the command line, there are cases where the built wheel is "cleaned" before the command runs.

rm -rf .tox
# works always
tox -r -e py311,py311-checks

# fails on the second target
rm -rf .tox
tox -e py311,py311-checks

The reason is:

• py311-checks has recreate = True
• py311 and py311-checks both rely on the same .pkg folder
• the .pkg folder is deleted after running py311 and before running py311-checks when -r is not specified on the command line

Environment

Provide at least:

• OS: macOS M2, python3.9,3.10,3.11

Minimal example

tox.ini

[tox]
requires =
    tox>=4
env_list =
    py{39,310,311}
    py{39,310,311}-checks
skip_missing_interpreters = true

[default]

[pkgenv]

[testenv]
description = "runs unit tests"
package = wheel
deps =
    pytest>=7
commands =
    python -c "print('should work')"


[testenv:py{39,310,311}-checks]
description = "checks"
package = wheel
recreate = true
# bug in tox: workaround: specify another package_env for this target
# package_env = .pkg-checks
deps =
    pytest>=7
commands_pre =
    python  -c "print('does not work')"

commands =
    # tests related to the package
    pytest --version
    pip list

Let me know if you need the package, but the one I tested against does nothing but print a message.

Possible workaround is to specify another package_env like the one commented out in the second target. The problem is that they can still do not share the same wheel.
