install-apks --allow-downgrade flag not working

**Describe the bug**
I'm using `bundletool` to generate `*.apks` from `*.aab` file, and then to install it to android device. Installing previous version (lower one than currently installed) results in error:
`E/SplitApkInstallerBase: Failed to commit install session 460987557 with command cmd package install-commit 460987557. Error: INSTALL_FAILED_VERSION_DOWNGRADE`

Using flag `--allow-downgrade` doesn't change anything.

**Bundletool version(s) affected**
Version: 1.6.1, 1.10.1

**Stacktrace**
Output:
```

**To Reproduce**
Building *.apks from *.aab with this command:
`java -Xmx1024m -jar lib/bundletool-all.jar build-apks --ks=*** --ks-pass=pass:*** --ks-key-alias=*** --key-pass=pass:*** --bundle "%1" --output "%1.apks" --local-testing`

Then installing using:
`java -Xmx1024m -jar lib/bundletool-all.jar install-apks --allow-downgrade --apks="%1"`
or
`java -Xmx1024m -jar lib/bundletool-all.jar install-apks --allow-downgrade=true --apks="%1"`

**Expected behavior**
If I understand correctly, build should be installed normally as usual.

**Known workaround**
Uninstall old version, install new one.

**Environment:**
Windows 10, `cmd.exe`, java version "1.8.0_231"

also checked on MacOS 12.1 with java version "1.8.0_333", same error.

**Additional context**
Using `--local-testing` flag while building `*.apks` because I'm using Google Play Asset Delivery. Don't know if that matters, because installing builds with higher version number than currently installed works like a charm.
