Feature/test utils with jest (#56)
* fix(test-utils): wallet summary tests * feat(test-utils): create tests for utils functions * chore(test-utils): rename utils to kebab case * chore(test-utils): move utils to right folder * fix(test-utils): utils import * fix(test-utils): bignumber toFormat function types * feat(test-utils): increase formatNumber test coverage
