pio lib update does not follow semver complaint version constraints.

[euphi]

As written in homieiot/homie-esp8266#470, platformio lib update updates locally installed libs even if the latest version does not match the semver compliant version match string.

E.g. if there is a dependency to lib@^1.0.0 a lib from the 1.0.x branch is installed initially, but later is updated to 1.1.x, when pio lib update is performed.

--> pio lib update shall follow the semver dependencies when looking for new libs.

BTW: I thnik this should not apply for global update (pio lib -g update) because pio can't know all locally installed projects and a project can install a older revision of a dependency locally.

Please re-test with pio upgrade --dev.

Thanks! Seems to run fine now.
