Doesn't work with AWS Federation enabled for CLI

[antontumasov-plutoflume]

Actual behaviour

I have the following in my credentials

...
[example]
role_arn          = arn:aws:iam::1234567890:role/example-role
source_profile    = example-profile
role_session_name = example
...

Running the tool spits out:

Cloud Resource Counter (v0.7.1) running with:
 o AWS Profile: example
 o AWS Region:  (All regions supported by this account)
 o Output file: resources.csv
 o Trace file:  example

Activity
 * Retrieving Account ID...Either the profile does not exist, is misspelled or credentials are not stored there.

I have exported AWS_PROFILE with the name which is successfully fetched by the tool but then it fails to work with assumed role.

Expected behaviour

The tool runs successfully with assumed role.
