--ndk-api appears twice

Description

When running buildozer android debug it seems like the --ndk-api appears twice when invoking the python3 -m pythonforandroid.toolchain create command.
For instance this is the log I'm getting:

# Run '/usr/bin/python3 -m pythonforandroid.toolchain create --dist_name=myapp --bootstrap=sdl2 --requirements=python3,kivy --ndk-api 9 --arch armeabi-v7a --copy-libs --color=always --storage-dir="/tmp/trash/.buildozer/android/platform/build" --ndk-api=21'

Ask you can see we have --ndk-api 9 and --ndk-api=21.
This seems to only happens when the android.ndk_api is defined in the buildozer.spec.
Basically the first one --ndk-api 9 is always present, while the second one --ndk-api=21is being picked up frombuildozer.spec`

I reckon this got introduced at the same time ndk-api param got introduced to buildozer in 6b004f9.

buildozer.spec

Command:

buildozer android debug

Spec file:
The spec file is the default master one after buildozer init with only two changes:

• android.ndk = 17c
• android.ndk_api = 21

#    -----------------------------------------------------------------------------
#    List as sections
#
#    You can define all the "list" as [section:key].
#    Each line will be considered as a option to the list.
#    Let's take [app] / source.exclude_patterns.
#    Instead of doing:
#
#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
#    This can be translated into:
#
#[app:source.exclude_patterns]
#license
#data/audio/*.wav
#data/images/original/*
#


#    -----------------------------------------------------------------------------
#    Profiles
#
#    You can extend section / key with a profile
#    For example, you want to deploy a demo version of your application without
#    HD content. You could first change the title to add "(demo)" in the name
#    and extend the excluded directories to remove the HD content.
#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*
#
#    Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug
