TLS logging eror when using only a store path

[julopezc-acciona]

Report

When declaring only the environment variable KEDA_HTTP_PROXY_TLS_CERT_STORE_PATHS keda-add-ons-http-interceptor fails to launch because it looks first in the folder KEDA_HTTP_PROXY_TLS_CERT_STORE_PATHS for a tls.crt file and fails when logging

Expected Behavior

Log without failure

Actual Behavior

Fails when logging the ignore key

Steps to Reproduce the Problem

1. Setup the env variable KEDA_HTTP_PROXY_TLS_CERT_STORE_PATHS but do not set KEDA_HTTP_PROXY_TLS_KEY_PATH nor KEDA_HTTP_PROXY_TLS_KEY_PATH
2. keda-add-ons-http-interceptor starts looking into the folder specified by KEDA_HTTP_PROXY_TLS_CERT_STORE_PATHS and if it finds no tls.crt here, it fails instead of recursively searching (there are certificates at $KEDA_HTTP_PROXY_TLS_CERT_STORE_PATHS/app1 and KEDA_HTTP_PROXY_TLS_CERT_STORE_PATHS/app2 though)
